[Recruitment agent] Details: 18042225118 Mr. Shu
main raw materials:
rare earth long afterglow luminous powder, polystyrene resin
1. Luminous Powder
it is a high-tech self-luminous product with rare earth metal elements activating alkaline earth aluminates and silicates. The temperature resistance reaches about 800 degrees. Its function is to absorb light and store light, absorb light at the bright place (more than half an hour), and shine in the dark. It has strong absorption capacity for short wave visible light with wavelength below 450 nm. By absorbing various natural light or artificial light, it can realize the self-luminous function in dark state and can be recycled, the initial high brightness of the luminescent material can reach more than 2-3 hours, the shoulder luminous curve is gentle, and the afterglow duration can reach 8-10 hours. Long afterglow luminous powder afterglow luminous time and luminance ratio traditional zinc sulfide system light storage powder is brighter, and it has faster absorption effect on sunlight and ultraviolet light, and can be recycled for many times.
2. Polystyrene resin (see Baidu Encyclopedia for details)
Polystyrene (Polystyrene, abbreviated as PS) refers to a polymer synthesized from styrene monomer through free radical addition polymerization, and its Japanese name is "ポ リ チ チ ン. It is a colorless and transparent thermoplastic with glass Inversion temperature higher than 100℃, so it is often used to make various disposable containers that need to withstand the temperature of boiling water, as well as disposable foam lunch boxes, etc. Ordinary polystyrene resin is an amorphous polymer. The side of polystyrene macromolecule chain is benzene ring, and the random arrangement of large volume side groups is benzene ring determines the physical and chemical properties of polystyrene, such as high transparency. High rigidity. High glass transition temperature, friability, etc. Expandable Polystyrene is made of physical foaming agent impregnated with low boiling point in ordinary polystyrene. It is heated and foamed during processing to make foam products. High impact polystyrene is a copolymer of styrene and butadiene, butadiene is a dispersed phase, which improves the impact strength of the material, but the product is opaque. Synditional polystyrene is of the same structure and is produced by metallocene catalyst. The new polystyrene variety developed has good performance and belongs to sexual engineering plastics.
Packing method:
bulk (25kg in a woven bag), bagged (1000G, 500g, 100g, etc. in a small bag), boxed. LOGO, bar code, etc. can be pasted outside the package according to customer requirements...
Please specify the color for shipment, which can be mixed set or clear color.
The luminous stones produced by our company are exported to the United States, Australia, Russia and European countries, and are favored by foreign customers.
Product value (the following dimensions and weights are reference values)
size: about 2CM
weight: about 2.2g
due to the irregular shape of stones, the above dimensions are only measured visually, and the weight is the gram weight of the sample. The data is for reference only. When shipping, the stone shape is shipped randomly.
Luminous principle:
luminous Stone light-emitting principle, luminous products absorb and store energy after being stimulated by visible rays of sunlight, lights, etc., which can not only naturally glow in the dark for a long time, but also absorb light repeatedly, and have a service life, reuse.
